Definition of overscan in US English:



  • The facility on some computer screens or televisions to adjust the picture size so that objects appear bigger but the edges of the picture are lost.

    • ‘I have read reports that you can still see the missing picture if you adjust the overscan on your TV, but for the rest of us, this is intolerable.’
    • ‘If you view on a standard television or you can adjust your overscan this may not be an issue, but for those without the capability it will be frustrating.’
    • ‘The image has been window-boxed to ensure a presentation uncompromised by video overscan.’
